Thanks to an exclusive and exceptional access to all the director's professional and personal archives, this documentary deciphers his work and the Ken Loach method: to make cinema a political weapon thanks to realistic films that move people. As a humanist, Ken Loach never stopped fighting against the implementation of neoliberalism at the end of the 70s with Margaret Thatcher coming to power in Great Britain. This apostle of subversion has twice won the prestigious Palme d'Or at the Cannes Film Festival for his films The Wind That Shakes the Barley (2006) and I, Daniel Blake (2016).
